SHB/SKYRAD/C1 - NIP Skystand vibration
DataStreams:shbskyrad60sC1.00, shbskyrad60sC1.a1, shbskyrad60sC1.b1
Description:
With winds gusting in excess of 20 knots, the stand may have
been shaking slightly. The snow	and ice	has melted away	around
the skirt of the ablation shield and underneath, so the Skystand
is not as sturdy compared to 2 weeks ago.  The NIP has a very
narrow view angle and a slight tilt of the platform may cause
the NIP to lose signal due to incorrect solar alignment. 

Since the exact amplitude of shaking is not known these data are
considered suspect.

Description:
The solar alignment dot was nowhere near the ring. After

During regular rounds a	few hours later, it was not 
sunny enough to tell.  When the solar alignment dot is

the direct solar irradiance.
